HAY-PRESS.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed May 4,1905. Serial No 258,807-

To all whom it may concern:

Be it known that I, EUGENE W. KELSEY, a citizen of the United States, and a resident of Collierville, in the county of Shelby and State of Tennessee, have invented a new and Improved Hay-Press, of which the following is to provide a single double-cam-faced operating-lever for the plunger-shaft which has a direct action and which operates with the least possible friction and which also acts upon the plunger-shaft almost immediately upon its return from its pressing-stroke.

Another purpose of the invention is to provide an improvement in the folder wherein it is rendered spring-controlled and to so construct the return mechanism for the plunger that the tension of the controlling-spring can be made strong or weak as occasion may demand.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improved press. Fig. 2 is a plan view of the press. Fig. 3 is a plan view of a portion of the operative mechanism for the plunger, drawn upon an enlarged scale and illustrating the plunger-shaft as partially pushed to the rear. Fig. 4 is a transverse section taken on the line 4 4 of Fig. 3, being also drawn upon an enlarged scale. Fig. 5 is a detail sectional view of a portion of the balingchamber and a transverse section through the folder. ger and its shaft and a slightly-modified form of operating-lever, and Fig. 7 is a side view of the delivery end of the press.

A represents the body of the press. In the construction of this body a bottom 10 is employed and a top 11, which extends to the back, but stops short at the front, so that the front upper portion of the body is open. Side pieces 12 are secured to the top and bottom at the front open portion of said body,

Fig. 6 is a plan view of the plunforming thereby a baling-chamber B, open at the front as well as at the top, and the said side pieces 12 extend rearward beyond the forward end of the top 11, as is clearly shown in Fig. 1. Flanged side pieces 12 extend down from the top at the rear of the complete side pieces 12, and corresponding flanged side pieces 12 extend up from the bottom; otherwise the rear portion of the body is open.

The body is braced and strengthened by placing crosspieces 14 at the top and at the bottom, which cross-pieces 1.4 are located at the rear ends of the body at its central portion and at its forward portion. The upper forward cross-piece 14 18 made to rest upon a front section 11 of the top of the body, as is shown in Fig. 1, which front section 11 extends from one side piece 12 to the other. The said cross-bars 14 are connected by brace-rods 15 at their ends, located at the outside of the body; but I desire it to be understood that additional means may be employed for strengthening the bo(ly-as, for example, is shown at 15 in Fig. 2.

A series of apertures 16 is made in the sides 12 of the baling-chamber B adjacent to the rear open portion of the said chamber, and keeper-springs 17 are secured at one of their ends to the outside of the side pieces 12 adjacent to each slot or aperture 16. The heads 17 a of these springs, which are of triangular construction, as is shown in Fig. 2, extend into the baling-chamber B through the said slots.

The forward end of the top 11 of the body A is given a downward and rearward inclination, as is shown in Figs. 1 and 5, and at this point a folder 19 is located. This folder is made of metal and comprises a horizontal upper body-section 19, a downwardly and rear-- wardly extending lip 19 at the forward end of the body-section, and arms 19, which extend rearwardly from the body-section and are pivoted on the said body, as is clearly shown in Fig. 5.

A cross-bar 14, which extends over the top 11 adjacent to its forward end, is provided with a chamber 21 in its under face and extends over the pivoted arms 19 of the folder. In this chambered portion of this said intermediate cross-bar 14 springs 22 are located, which have bearing upon the pivoted arms 19 of the holder, serving to hold the folder 19 in its lower or normal position, (shown by positive lines in Fig. 5;) but as the plunger ICO to be hereinafter described operates in the said baling-chamber B it lifts the folder 19 to i the dotted position shown in Fig. 5 when the said plunger is about finishin its pressingstroke.

At the rear end of the body A plates 23 are hinged to the inner faces of the top and bottom sections 11 and 10, as is shown in Fig. 1, and springs 24 are made to bear against the rear or free ends of the said plates 23. These plates are adapted to further compress a bale 1 as it leaves the said body A.

The lower sills of the body A extend beyond its forward open end, as is shown at 13 in Figs. 1 and 2, and extension-sills 25 are secured to the sills 13 in any suitable or approved manner, which extension-sills are carried as far to the front as may be desired. A platform 26 is constructed on the forward end portions of the extension-sills 25, as is shown in Fig. 2.

A rear axle 22 is secured to the bottom portion of the body A below the baling-chamber B, and wheels 23' are removably placed on the said axle 22. From the forward end of the platform 26 a bracket 27 is projected, to which the forward. truck 28 is pivoted, carrying the forward wheels 29, which are likewise removable, as when the press is in use the axles rest upon the ground, as is shown in Fig. 1, so that the horse or team employed in the operation of the press may readily step over the extension-sills 25 and parts carried thereby.

. A bearing 30 is secured upon the platform 26 near its forward end and about centrally between its sides, and in this bearing the pivot-pin for an operating-lever C is mounted, which pivot-pin passes through the central portion of the said lever. This lever C is provided with cam-surfaces 31 and 32 at its ends, facing in opposite directions, and the said cam-surfaces are more or less semi-elliptical, and there is more or less of a depression where they meet the straight lines of the lever C.

Draft-arms 33 are secured to the operatinglever C at its upper portion near each endand the free ends of the said draft-arms are broughttogether and are secured in any suitable or approved mainier, and where the said draft-arms come together a clevis 34 is attached, to which a team or a single horse is attached, as occasion may demand. In front of the said. bearin 30 a brake-spring 35 is secured on the platform 26, which brakespring is secured at its left-hand end to the said platform, its right-hand end portion being free and upwardly curved and then horizontally carried toward the right-hand side of the platform, as is shown in Figs. 2 and 3.

A plunger 36 is adapted to slide in the baling-chamber B. This plunger 36 has its right-hand side 37 more or less beveled from its inner face in direction of the left-hand side, as is particularly shown in Fig. 6, and a socket 38 is formed on the forward face of the said plunger 36, preferably made of metal and comprising four members, and into this socket 38 the rear end of the plunger-shaft 39 is entered and secured.

At the forward end of the plunger-shaft 39 These guide-rails 43 extend from the right-- hand side of the platform at a point just in front of the right-hand cam of the operatinglever C when said operating-lever is in its normal position (shown in Fig. 2) and the said guide-arms 43 are curved in direction of the left-hand side of the platform, terminating at or about its center. The guide-rails 43 are connected at their ends, so that the plungershaft 39 is compelled at its forward end to fol low the said guide-rails 43 and cannot leave them.

At the outer face of the right-hand extension-sill 25 a horizontal bracket 44 is secured in any suitable or approved manner, and this bracket extends parallel with the said sill and is provided with a longitudinal slot 45, as is shown in Fig. 3. A block 46 is made to travel in the said slot 45 of the bracket 44, as is shown in Figs. 3 and 4, and a screw-rod 47, which is preferably integral with the block, is made to enter an interiorly-threaded tube 48. A spring 49 is coiled around the said tube and the said screw rod or bar 47, having bearing at one end against the rear face of the block 46, being secured. at its opposite end to the right-hand side of the plunger-shaft 39, and the said spring 49 is likewise secured to the tube 48 at a convenient point in its length, preferably at its forward end. This spring is placed under compression when the plunger is forced rearwardly in the baling-chamber B by the action of the operatingdever C, and when the plunger-shaft 39 is relieved from engagement with a cam on the said operatinglever C the spring 49 acts to force the said shaft 39 and the plunger.36 to their normal positions, at which time the plunger is at the forward end of the baling-chamber B, as is shown in Fig. 1; but the said spring does not commence to act until the plunger is within six or eight inches of the finish of its rearward stroke.

The folder 19 serves to prevent the hay at the top of a bale from crowding back again into the baling-chamber, and the springs 17 serve the same purpose with respect to the side portions of the compressed mass of hay.

In Fig. 6 I have illustrated a slightly-modi- --fled form of the operating-lever C, which op erates, however, in the same manner. In the modified form of the operating-lever a body block is employed of rectangular shape, and upper and lower bars 51, of metal, are made to extend diagonally the length of the said block 50 and beyond its ends. From opposite sides of the bars 51 near their ends cars 52 are projected, and between these ears 52 friction-rollers 53 are mounted to turn, so that these friction-rollers 53 are at opposite sides of the block 50. Between the end portions of the bars 51 larger friction-wheels 54 are mounted to turn so that the smaller friction-rollers 53 and adjacent larger frictionrollers 54 accomplish the same result as the cam-surfaces 31 and 32 shown in the other views and represent practically the same construction. The draft-bars 33 are secured to the block 50 at its upper face, as is also shown in Fig. 6. In this figure instead of the friction-roller 41 at the end of the plungershaft the said shaft is provided with a bend or crank-arm 40, with which the rollers of the operating-lever engage.

The cams shown in Figs. 2 and 3 can be made in one piece in any approved form, so that the relative positions of the antifrictionrollers and pivot are preserved.

In operation, as the draft arms or bars 33 are moved by means of a team or otherwise, the operating-lever C is made to turn upon its pivot, and supposing the plunger-shaft 39 to be in its normal position, (shown by positive lines in Fig. 2,) having its friction-roller 41 in engagement with the cam 31, where it connects with the lever C as the said lever is turned, the cam-surface 31 will force the shaft 39 rearward, and said shaft will cause the plunger 36 to slide also rearward in the bailing-chamber B, compressing the material fed to said chamber. WVhen the plunger 36 has reached a true horizontal position about midway between the extension-sills 25 and the end of the cam 31 engages with the roller 41 of the plunger-shaft 39, as is shown by dotted lines in Fig. 2, a further swinging movement of the lever will permit the plunger-shaft 39 and attached plunger to move quickly forward by the action of the spring 49, as such spring was placed under tension as the plunger was forced rearward on its working stroke. This forward movement of the plunger-shaft would tend to accelerate the speed of the operating-lever 0, since the roller of the plungershaft would travel along the plain body-surface of the lever, and in order to slightly check this inclination to a sudden movement on the part of the lever the brake-spring 35 It will be observed that as the plungershaft 39 is initially inclined to the right-hand side of the machine the plunger 36 in its normal position has a slight cant in the baling-chamber, and the bevel 37 is provided at the right-hand side of the plunger 36 in order that the said plunger may assume such position without frictional engagement with the side walls of the baling-chamber.

In Fig. 7 I have illustrated a tension device E,which I preferably employ for connecting the upper and lower members of the press at its delivery end. This device consists of two parallel and substantial short bolts 55 and 56, having heads at one end and nuts 57 at the other end, and these bolts are loosely passed through end cross-heads 5S and 59 and an intermediate cross-head 60. A main bolt 61 is loosely passed through the central portion of the lower cross-head 59 and the intermediate cross-head and also through the bottom of the press and is provided with a nut 62 at its lower end. A second main bolt 63 is passed through the upper cross-head 58 and through the upper portion of the press, being provided with a nut 64 at its upper end. A spring 65 is coiled around the lower bolt 61, which spring has bearing against the lower and intermediate crosss-heads. Thus the press is always under tension at its delivery end, and the bale is also subjected to tension upon leaving the press. The tension may be increased or decreased, as desired, by adjusting the said nuts.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a hay-press, a body portion provided with a baling-chamber, a plunger mounted to slide in said chamber, a forward extension from the said body, a lever centrally pivoted upon said forward extension, provided with cam-surfaces at its ends facing in opposite directions, which cam-surfaces meet the plain side edges of said lever more or less abruptly, draft-arms secured to the said lever between its ends, a shaft secured to the said plunger, having a roller at its outer end, an apertured cross-head secured to the bottom portion of the said plunger-shaft at its outer end, and segmental guide-rails secured to the said eX- tension, which guide-rails freely pass through the apertures of the crosshead, and atension &
